NAME

curl_multi_cleanup - close down a multi session

SYNOPSIS

#include <curl/curl.h>

CURLMcode curl_multi_cleanup(CURLM *multi_handle);

DESCRIPTION

This function is the opposite of curl_multi_init(3). Cleans up and removes a whole multi stack. It does not free or touch any individual easy handles in any way - they still need to be closed individually, using the usual curl_easy_cleanup(3) way. The order of cleaning up should be:

1 - curl_multi_remove_handle(3) before any easy handles are cleaned up

2 - curl_easy_cleanup(3) can now be called independently since the easy handle is no longer connected to the multi handle

3 - curl_multi_cleanup(3) should be called when all easy handles are removed

Passing in a NULL pointer in multi_handle makes this function return CURLM_BAD_HANDLE immediately with no other action.

Any use of the multi_handle after this function has been called and have returned, is illegal.

EXAMPLE

int main(void)
{
  CURLM *multi = curl_multi_init();

  /* when the multi transfer is done ... */

  /* remove all easy handles, then: */
  curl_multi_cleanup(multi);
}

RETURN VALUE

CURLMcode type, general libcurl multi interface error code. On success, CURLM_OK is returned.
